citizen of the United States, and a resident of Newton, in the county ofMiddlesex, Commonwealth of Massachusetts, (Whose post-oiiice address is.care of Carr Fastener Company, Cambridge, Massachusetts,) haveinventedan Improvement in Fasteners, of which the following description,in connecd tion with the accompanying drawings, is a specication, likecharacters on the draw ings representinglike parts. l Y `This inventionpertains to improvements in separable fasteners, and more particu?larly, though not exclusively, to improvements in fasteners for useinconnection with the attachment of automobile curtains to the The stud 9is-...preferably provided i' bodies of automobiles.

Y Ventrance or withdrawal is made in a direction substantially axial ofthe stud and socket; but if force is exerted in a direction notsubstantially axial oi." the stud y and socket, the shoulder 15 will enage the pro- Y and prevent withdrawal of the stud from the socket.

The operation of the fastener .device is very simple, involving merelythe entrance of the stud into the socket by the exertion of pressure ina direction axialof the stud and socket to spring the annular ring 12over the head portion of the stud which is beyondthe groove 11.Similarly withdrawal of the stud from the socket may be effected byexerting suficient force in a direction substantially axial of the studand socket to lpring open the resilient jaw means 12,

ereby to permit the passage of the head i 4 of the stud past such jawmeans.

If, for, any reason, the socket O'ets out of order, it can beeasilyunscrewed vfrom the outside of the body of the car and a newsocket inserted yin its place, without thev necessity for interferencewith the interior finish ofthe automobile body.

While I have shown and described one embodiment of my invention, it willbe understood that changes involving omission,

alteration, ,substitution and reversall of -parts,' and Veven changes inthe mode v of operation, may be made without departing fromV the scopeof my invention, which is best defined the following claims.
